The company successfully implements the use of chemicals in municipal sewage treatment facilities (sewage treatment plants). Physico-chemical treatment is accepted worldwide, and is widely used in large facilities.
In a large number of facilities in Canada, the USA and Scandinavia, the treatment is only physico-chemical due to temperature limitations. Is a technological and economic breakthrough in Israel.
Beyond the infrastructure constraints of the sewage treatment plants (population is growing and the flows to the sewage treatment plants are growing accordingly) and the economic savings inherent in the technology, there is a regulatory aspect that has worsened in recent years and makes the use of chemicals more common.
The use of chemicals in municipal wastewater treatment facilities enables the following objectives to be achieved:
● Immediate increase in the capacity of the sewage treatment plant, without the need to build additional treatment lines and basins.
● Improving the quality of effluent for the purpose of returning water to agriculture and industry.
● Reducing the concentration of phosphorus in accordance with the standard requirements with a minimum investment.
● Removal of phosphorus to prevent the formation of strobitus in the sewage treatment plant lines.
● Removal of heavy metals and fats to prevent biomass poisoning.
● Color removal, and secondary effluent adjustment for UV disinfection
● Improving the function of the facility: saving on electricity costs and sludge removal.
● Reducing investment in the construction of new facilities, while combining chemical and biological treatment.
● Providing a seasonal solution to various problems in the sewage treatment plant: sedimentation, certification and squeezing problems caused by changes in biomass, receiving abnormal currents and / or temporary shutdown of parts in the sewage treatment plant and more.
The emphasis in the solutions proposed by S² is on their being economically viable, immediately available and scientifically proven. S² engineers will perform performance analysis of the facility including laboratory tests, facility inputs and ongoing monitoring. After analyzing the data, the company will recommend the optimal application based on the existing situation.
If there is justification for the changes, the company's engineers assimilate the technology while analyzing the function of the facility in real time and accompanying the professional staff of the Sewage Treatment Plant.
Increasing the capacity of existing facilities
Chemically Enhanced Primary Treatment (CEPT) has the potential to increase the capacity of existing lines in the treatment plant up to 30% and can be applied immediately. .
For CEPT application, increased initial sedimentation, a number of significant advantages:
● Increasing the rate of settling: according to facility planners 4 times more than natural settling.
● Improving the initial sludge density (higher solids concentration)
● Reducing organic loads on the biological reactors - reduction in oxygen consumption (electricity costs) and reduction in the amount of WAS
● Improving digestion by increasing the ratio of primary sludge to WAS - increasing methane output.
● Application of joint sludge certification (if appropriate for the infrastructure in the sewage treatment plant)
● Significant reduction in sludge removal due to reducing the amount of dry sludge and improving solidification.
● Savings in polymer consumption and operation of the firming system.
