7000 lpd Industrial Laundry Effluent through Reed-beds
The Challenge: Laundry effluents are highly concentrated in COD due to various chemicals and detergents used, which can destroy vegetation and top-soil characteristics if left untreated.
The Solution: We implemented a 7000 lpd vertical flow reed-bed system utilizing a two-stage bed and a final polishing tank. Using a variety of plant species, predominantly successful typha grass, the system successfully reduced COD levels from 1950 mg/l to 93 mg/l.

8000 lpd Kitchen Waste Water using Anaerobic-Aerobic Method (NOWA)
The Challenge: Effluent from hotels and restaurants qualifies as high-intensity gray water containing TSS, oil, and grease.
The Solution: Utilizing CSIR's patented technology, the system applies micro-filtration to remove TSS and a grease trap for complex hydrocarbon chains, followed by a series of power-free anaerobic and aerobic chambers (except for aeration). COD was reduced from 2400 mg/l to under 100 mg/l, and BOD from 523 mg/l to under 30 mg/l for agricultural use, with further sand-charcoal filtration enabling reuse for floor cleaning.

10000 lpd Canteen Waste Water using Anaerobic-Aerobic Method (NOWA)
The Challenge: Similar to hotel wastewater, canteen runoff contains oil and grease that must be removed prior to entering anaerobic chambers.
The Solution: Using the patented NOWA process flow—consisting of five anaerobic chambers, one aerobic chamber, and a clarifier—we successfully reduced COD from 1983 mg/l and BOD from 478 mg/l down to safe disposable standards.

4000 lpd Dung De-water Slurry using Reed-Bed System
The Challenge: While dung extracts are valuable for fertilizer, the resulting de-watered slurry is highly septic and voluminous. Reed-beds typically face constraints with TSS passing into syphon mechanisms.
The Solution: We designed a system featuring micro-filtration, a sedimentation tank, and a header mechanism to control flow. The pit utilizes a combination of vertical flow top-down and bottom-up designs, complete with a backwash mechanism to ensure easy maintenance.

700 lpd Milk Can Wash-water through Tower Reed-Bed System
The Challenge: Washing milk cans used for transport results in light-intensity gray water. Space constraints and the low volume of wash water limit the use of traditional reed-beds.
The Solution: We deployed a space-saving tower reed-bed system designed for accelerated filtration efficiency. Featuring four filter beds with carefully selected plant species, preceded by a sedimentation and coagulation tank, the system reduced BOD (57 mg/l) and COD (193 mg/l) to disposable standards, concluding in a final polishing tank.
