This letter certifies that NatureVel-WW products from Clover Organic Pvt. Ltd. were used in a 23 KLD STP plant. Within 11 days of treatment, the products reduced pollution loads remarkably by lowering BOD to under 2 mg/L, COD to 6 mg/L, and TSS and TDS by 40% on average while raising DO levels to 7.5 mg/L. Total coliform was reduced to 27 MPN/100 ml and faecal coliform fell below detectable levels, reducing foul odour. The treated water is used for gardening. Clover Organic provided good after-sales service by training personnel and maintaining contact to address minor issues.
