In
the first quarter of 2000, the Company recorded special charges of $250 related to the first quarter 2000 restructuring of several corporate functions. For the nine months ended
September 30, 2000, the Company expended $225 for workforce reduction severance costs. The remaining $25 is anticipated to be expended by December 31, 2000.

In
fiscal year 1999, the Company recorded special charges of $1,233 for corporate restructuring and consolidation of operations. For the nine months ended September 30, 2000,
the Company expended $205 for workforce reductions and $645 for facility closing/consolidation costs. The remaining $383 is anticipated to be expended by December 31, 2000.

The
Company has $14,500 of goodwill recorded as of September 30, 2000 associated with the second quarter 1998 acquisition of Membrex Corp. (Membrex). Safety Kleen (SK), the
principal customer for the Membrex products, filed for Chapter 11 bankruptcy in June of 2000. As a result, second and third quarter 2000 sales to SK of $700K and $750K, respectively, were
substantially below first quarter 2000 sales of $2,100. SK has continued to order product and parts at reduced levels and future sales levels are uncertain and could be minimal.

The
Company has a contract with SK that provides some exclusivity to SK for certain Membrex products. Within the exclusivity terms, the Company is working with SK-Europe,
a SK-U.S. affiliate that is not in bankruptcy, and anticipates sales by the fourth quarter of 2000 when ongoing European beta testing is complete. The Company is investigating alternative
approaches to market as allowed by the

5

---

contract for these products. Additionally, the Company is continuing to investigate new applications for the technology acquired from Membrex. Inventory related to the Membrex products was $1,900
while outstanding receivables from SK were current at September 30, 2000. The Company is monitoring the Chapter 11 bankruptcy proceedings to determine any further financial impact to the
Company.

Operating
results for the three months or nine months ended September 30, 2000, are not necessarily indicative of the results that may be expected for the full year 2000.

These
statements should be read in conjunction with the financial statements and related notes included in the Company's Annual Report to shareholders and Form 10-K
for the year ended December 31, 1999.

SALES

Sales for the third quarter ended September 30, 2000 of $47,592 increased 1.5% from sales for the third quarter of 1999.
Year-to-date 2000 sales through September increased 6.8% over the corresponding 1999 level. The third quarter 2000 Specialty Filtration & Separation, Process Water
Treatment and Household Water Treatment segment sales were 40%, 40% and 20% of total sales, respectively. Third quarter 1999 included $1,626 in sales from products produced at manufacturing facilities
closed in 1999. Globally, all foreign markets (Asia/Pacific, Euro/Africa and Latin America) experienced improved sales activity during the first nine months of 2000 compared to the same period of
1999. The deterioration of the Euro in comparison to the U.S. dollar negatively impacted third quarter of 2000 sales by approximately $580 or 1.2%.

GROSS MARGIN

Gross margin for the third quarter of 2000 was 29.6% compared to 31.6% for the corresponding period in 1999. The gross margin for the nine months ended
September 30 was 31.4% in 2000 compared to 33.6% for the same period in 1999. The third quarter of 2000 decrease in gross margins is partially due
to the $580 (0.8%) negative sales impact of the Euro deterioration and one-time costs of $400 (0.9%) to relocate product, equipment and personnel which reduced gross margins from 31.3% to
29.6%. The first nine months of 2000 decrease in gross margins is partially due to lower utilization and production issues at certain manufacturing facilities. To reduce excess manufacturing capacity,
reduce costs and improve gross margins, one facility (Rockland, Massachusetts) was closed on December 31, 1999, and production activities at another facility (Phoenix, Arizona) ceased on
September 30, 2000.

---

The Company is also relocating certain production and product capabilities in efforts to focus its factories and eliminate duplicate capabilities and the associated cost and overhead
structures. Six such relocations were completed during the first nine months of 2000 and others are scheduled for completion before the end of 2000. The production issues identified in 2000 are being
addressed and changes have been instituted during the first nine months of 2000. Production scrap rates improved 40% in the third quarter of 2000 compared to the first quarter of 2000.

A
product mix shift within Process Water and Filtration and Separation segments also decreased third quarter and year-to-date 2000 gross margins in comparison
to the same periods in 1999.

OPERATING EXPENSES

Operating expenses increased to 25.6% of sales in the third quarter of 2000 compared to 25.3% in the third quarter of 1999. The increase is attributed to the
Special Recovery of $1,080 (see Special Charges/ Recovery discussion) recorded in the third quarter of 1999. Excluding the Special Recovery, third quarter 2000 operating expenses decreased $781 (2.1%
of sales) from the same period in 1999. The third quarter 2000 decrease is primarily the result of reduced Selling, General and Administrative expenses from the recent corporate restructuring.

Operating
expenses increased to 26.7% of sales for the nine months ended September 30, 2000 compared to 26.4% for the same period in 1999. The increase is attributed to the
acquisition of Zyzatech in July 1999 and the third quarter 1999 Special Recovery of $1,080 (see Special Charges/ Recovery discussion). Excluding these items, nine months ended
September 30, 2000 operating expenses as a percent of sales decreased to 26.0% compared to 27.2% for the same period in 1999.

SPECIAL CHARGES (RECOVERY)

In first quarter 2000, the Company recorded special charges and recoveries that netted to zero. Special charges included a $250 recovery of inventory accruals
primarily due to gains recognized on the sale of inventory at the Company's Rockland, Massachusetts manufacturing facility. The special charges also included $250 of workforce reduction severance
costs related to the first quarter 2000 restructuring of several corporate functions. These special charges (recovery) are summarized below:

In
third quarter 1999, the Company recorded a net special recovery of $270 ($178 net-of-tax or $0.01 per share assuming dilution). The recovery included a
$1,665 gain on the sale of an operation and a recovery of $215 related to the second quarter 1998 special charge. The special charges also

See
Notes to Consolidated Financial Statements for updates related to special charge activity.

OTHER INCOME (EXPENSE)

Other expense decreased by $274 in the third quarter of 2000 versus the same period for 1999. The decrease is primarily the result of $635 pretax gain ($0.03
per diluted share after tax) recognized on the sale of marketable securities in the third quarter of 2000. This compares to $150 pretax gain ($0.01 per diluted share after tax) recognized on the sale
of marketable securities in the third quarter of 1999. Offsetting these gains was a $258 loss on the translation of the net assets of a foreign operation as a result of the strengthening U.S. dollar.
Net interest expense for the third quarter of 2000 exceeded the same period of 1999 levels by $63.

Year-to-date
other expenses decreased $1,835 in 2000 compared to 1999. This reduction is primarily due to $2,723 pretax gains ($0.13 per diluted share after
tax) recognized on the sale of securities during the first nine months of 2000. The first nine months of 1999 included a gain of $270 on the sale of land and buildings from a closed production
facility that was not repeated in 2000. Net interest expense for the first nine months of 2000 exceeded the same period of 1999 levels by $321.

INCOME TAXES

The effective tax rate for the third quarter of 2000 was 29%, reducing the year-to-date 2000 effective tax rate to 33.0% based on the
forecast for the full year. This rate is comparable to 33.0% in the same periods of 1999. However, this represents a significant change from the tax rate percentage recognized in calendar year 1999,
due primarily to the non-deductible $3,500 goodwill asset impairment special charge related to AquaMatic products recorded in the fourth quarter of 1999.

NET INCOME

Net income for the quarter ended September 30, 2000 was $1,019 compared to $1,458 for the quarter ended September 30, 1999. Net income per
diluted share for the quarter was $0.07 compared to $0.10 for the same period last year.

Year-to-date
2000 net income was $4,459 compared to $5,179 for the same period last year. Net income per diluted share year-to-date was
$0.31 in 2000 compared to $0.36 in 1999.

LIQUIDITY AND CAPITAL RESOURCES

As of September 30, 2000, the Company had cash, cash equivalents and marketable securities of $5,240 versus $15,814 at December 31, 1999. This
decrease in cash, cash equivalents and marketable securities is the result of the Company liquidating $11,631 of its marketable securities portfolio during the first nine months of 2000. The current
ratio was 1.6 at September 30, 2000 and at year end 1999.

9

---

The Company's long-term debt decreased from $32,201 at December 31, 1999 to $24,232 at September 30, 2000. This decrease was the result of the Company using
proceeds from marketable security liquidations to pay down debt levels. The Company's current debt increased in the first nine months of 2000 to fund working capital increases related to the growth in
sales. The Company's borrowings outstanding against its $24,000 revolving line of credit increased to $19,000 as of September 30, 2000 compared to $18,500 as of December 31, 1999.

In
order to reduce the expense of carrying an unused revolving line of credit, the Company entered into a loan agreement amendment in the first quarter of 2000. This reduced the
Company's unsecured revolving line of credit to $30,000 from $35,000. In the second quarter 2000, the Company negotiated the release of collateral arrangements with its lenders associated with $10,000
of its marketable securities portfolio. As a result, the Company liquidated $7,900 of its marketable securities portfolio and used the proceeds to reduce aggregate debt levels, fund current operations
and enter into a loan agreement amendment that reduced the Company's unsecured revolving line of credit to $24,000 from $30,000

The
Company believes that its current cash and investments position, its cash flow from operations, and amounts available from bank credit will be adequate to meet its anticipated
cash needs for working capital, capital expenditures, and potential acquisitions during the foreseeable future.

REVIEW OF INDUSTRY SEGMENTS

The Company designs, manufactures and markets equipment, systems and components used in the processing and handling of fluids. In 2000, the Company changed the
focus of its reporting structure from a two segment, product focused structure to a three segment, market focused structure.

The
three market segment structure was established to provide strategic leadership within the three major market segments in which the Company conducts business. The new structure was
implemented on January 1, 2000. Restatement of 1999 financial results under this method of reporting has been completed and will be disclosed comparatively in financial reports. Restatement of
results prior to 1999 under this method of reporting has been deemed impracticable due to the costs of obtaining and unavailability of certain financial information.

The
Specialty Filtration and Separations segment includes products such as filter cartridges, membrane elements, membranes, instruments and laboratory products. The Process Water
Treatment segment includes products such as pumps, housings, valves, controls, reverse osmosis/ultrafiltration (RO/UF) machines, ozonators and water treatment systems used for industrial, commercial
and municipal applications. The Household Water Treatment segment includes products such as valves, controls and home reverse osmosis membranes used in residential water softening and water
purification. Each segment is currently supported by several manufacturing facilities, an individual sales force and various corporate functions. The segments do not have separate accounting,
administration, or manufacturing functions.

All
three segments experienced internal sales growth in both the third quarter ended and first nine months ended September 30, 2000 compared to the same periods in 1999.
Process Water Treatment segment growth for the nine months ended September 30, 2000, was primarily the result of sales from Zyzatech acquired on July 1, 1999. Q3-99 Process
Water Treatment segment sales included $750 of sales from products produced at manufacturing facilities closed in 1999.

Gross
profit margins and operating income margins in the Specialty Filtration and Separations and Process Water Treatment segments were lower in the third quarter ended and first nine
months ended September 30, 2000 compared to the same periods in 1999. The Specialty Filtration and Separation reductions were primarily related to production issues, including increased
manufacturing scrap and variances at certain manufacturing locations. Also, certain manufacturing locations were impacted by lower production levels which resulted in unabsorbed overhead. In addition,
an unfavorable sales mix contributed to the reduced margins.

The
Process Water Treatment gross profit margin reductions were primarily related to increased material cost, continued price competition and non-recurring production
move-related costs of $400.
Operating expenses in Q3-00 were slightly lower than previous quarters; however, operating expenses for the nine months ended September 30, 2000 exceeded the same period in 1999.
This increase, which reduced operating income margins in 2000 compared to 1999, is the result of the segment reinvesting in sales and marketing resources in an effort to utilize remaining surplus
manufacturing capacity.

Gross
profit margins and operating income margins in the Household Water Treatment segment improved in the third quarter ended September 30, 2000 compared to the same periods
in 1999. The improvement was primarily related to the reduction of production issues that included decreased manufacturing scrap and variances, at a certain manufacturing location. Operating expenses
were also reduced for the comparable period that also favorably impacted operating margins. Gross profit margins for the nine months ended September 30, 2000 were below those of the comparable
period in 1999. This decrease was primarily the result of production issues that included increased manufacturing scrap and variances during the first six months of 2000, at a certain manufacturing
location. Operating

11

---

expenses for the same nine month period comparison were lower in 2000 which resulted in improved year-to-date 2000 operating margins.

Currently,
management does not report the balance sheet or any cash-generating measurements by such segments.
