New biodegradable antiscalant product for the treatment and reuse of wastewater with membrane systems

The growing need for water and the current shortage of resources means taking measures to promote water reuse. An alternative resource is regenerated water. When considering the use of this resource, it is necessary further improvement of the quality of treated water for reuse. In this framework, the use of membrane bioreactors (MBR) coupled to a reverse osmosis (RO) is becoming an increasingly attractive option for the treatment and reclamation of wastewater.

In the present study we developed the antiscalant product ADIC R0-44 (ADICGREEN RANGE) which is effective in protecting the membranes of reverse osmosis systems used for the purified waste water treatment. This new antiscalant product is especially effective for controlling precipitation of calcium phosphate and calcium carbonate, without acid dosing to prevent precipitation of calcium phosphate. Standard Operating data of the pilot plant wound reverse osmosis membrane, and the results of the autopsies of different elements confirmed the efficacy of antiscalant developed.

The antiscalant ADIC R0-44 AdicGreen is environmentally friendly because it does not contain phosphorus or nitrogen in their composition. New antiscalant immediate biodegradability studies were performed and the results indicated that it can be classified as biodegradable.

Specific software was developed to calculate the optimum dosage of antiscalant according to feed water composition, temperature and conversion of reverse osmosis, optimizing performance and minimizing plant operating costs.
