6. TREATMENT METHODS Screening‚ grit removal‚ flow equalization‚ sedimentation‚ or dissolved air flotation are used to reduce suspended solids (SS) load from sugar industry wastewater. Biological treatment includes aerobic and anaerobic process. Except biological methods‚ physico-chemical methods are also used for sugar industry wastewater treatment. 6.1 Biological methods Since‚ sugar industry wastewater contains mostly sugars and volatile fatty acids‚ which are easily biodegradable‚ therefore all

purposes‚ such as agricultural and landscape irrigation‚ industrial processes‚ toilet flushing‚ or groundwater basin replenishment‚ is growing in response to environmental and economic concerns. One of the key factors involved in recycling wastewater treatment plant (WWTP) effluent for another use is the need to reduce total dissolved solids (TDS). This is often done by using a reverse osmosis (RO) system‚ which relies on pressure differential to force a solution (in this case‚ water) through a membrane

• Incensement of total capacity of treatment plant and improvement to water quality can be achieved vary easily. It’s possible due to lamella settlers‚ which provide high treatment in smaller footprint and high degree of settling capacity also process is more efficient and faster than conventional treatment with sedimentation tank. That because of one of most important feature of lamella settlers‚ are series of inclined plate which the suspended particles goes down with water flow‚ where solid particles
