The number of crude palm oil factory (CPOF) in Indonesia has already increased rapidly in the last fifteen years. In the same period, expansion of the palm plantation has also been continuing and growing, but unfortunately the accelerated growth is not same as the development of the wastewater treatment technology and its proper applications. Many CPOF in Indonesia have not a good wastewater treatment plant (WWTP). In fact they cause terribly environmental problems, especially related to surface water pollution. BOD content in the effluent of most CPOF is between 35,000 to 46,000 ppm and in the effluent of their WWTP it is much more than 100 ppm. Therefore it needs to propose a treatment system which can guarantee to reduce all pollutants till a value matching with the environmental quality standard. Based on the research result assessed by BPPT, an ideal WWTP suitable for CPOF is promoted to be considered as one very good alternative which is better applied for all CPOF in Indonesia. The stages and processes are showed in the second figure. Key words : Ideal treatment, CPOF wastewater

In line with fast growth of populations in urban area the discharged waste water from daily activities have caused contamination of ground water and also surface water. Unbalance between distribution of source and usage of water have caused unbalance between supply and demand. Therefore, new innovation in the case supply of raw water has come to important attention. One of the alternatives which getting much attention in many state in world is to use recycle wastewater especially municipal wastewater as one source of raw water for water supplySeveral things which need to be paid attention in the case of usage of recycle wastewater are consistency of the treated water quality as according to enabled condition. In usage of recycle wastewater to be used as clean water supply there is several categorize of contaminant which must be paid attention peculiarly namely for example organic contaminant including pesticide, pathogenic bacteria, parasite, virus and also heavy metal contaminant for example mercury, lead, chrome, cadmium etc. Therefore the treatment process must be done neglectlessly with control of quality which able to be justified.One of the concept for processing of urban wastewater to be made clean water is use combination of primary treatment, secondary treatment with biological process continued by advanced treatment by physico-chemical process for example covering clarification process, nutrient removal, recarbonation, filtration, adsorption with activated carbon, ion exchange process, and also demineralization with process of reverse osmosis and also ozonization and chlorination. With these processes combination can treat wastewater yield treated water with quality of as drinking water.This paper explained some example of wastewater treatment process for recycle wastewater which have been applicated in some state. One of the example of wastewater recycle process using combination of biological process continued with ultra filtration process, reverse osmosis process, and disinfection by ultraviolet, and also pH control such as those which have been conducted by NEWATER Factory, Singapore.

Authors: Nugroho Rudi 
Published: June 2020

Effect of nitrite on denitrification of synthetic wastewater using autotrophic bacteria was evaluated in both batch suspension and continuous packed column runs. Emphasis was placed to clarify the minimum concentrations of nitrite and nitrous acid that inhibit the denitrification rates. Batch suspension runs were conducted by mixing acclimatized denitrification sludge and synthetic wastewater in an Erlenmeyer flask. In continuous runs, denitrification sludge was loaded to a column packed with sulfur and limestone. The nitrite inhibition could be explained satisfactorily by substrate non-competitive inhibition model. The minimum concentration of nitrite which inhibits the nitrate and nitrite removal rate lowered with decreasing pH. In suspension runs, the minimum concentration of nitrous acid which inhibited the nitrite removal rate was 0.043 g-N/m3, while the nitrate removal rates was inhibited below 0.012 g-N/m3. Both in suspension and continuous packed column runs, nitrate removal was more sensitive against nitrite increase compared with nitrite removal. The minimum concentration of nitrite which inhibited nitrate removal rate in continuous packed column runs was lower than that in suspension runs.

Published: June 2020

An autotrophic denitrification system was developed for treatment wastewater from steel industry. The aim was to evaluate the kinetics and capability of the system in reducing nitrate content in such industrial wastewater. The experiments were conducted in batch suspension and continuous runs. The denitrification kinetics in suspension runs obeys first order reaction with the rate constant k1 and k2 were determined to be 0.014 and 0.004 g-N/m3.d, respectively. The continuous runs used a column packed with mixture of granular sulfur and limestone. The microbes of Thiobacillus denitrificans were attached on the surface of granular sulfur in the form of biofilm. The biofilm thickness was investigated to be approximately 40 μm. The denitrification kinetics in the packed column obeys half-order reaction with the rate constant k of 0.172 g-N1/2.m1/2/(kg-S.d). The lower denitrification extent of industrial wastewater compared with the synthetic wastewater might be due to the lack of alkalinity.
