RWI-8000

 

The treatment of wastewater is a fundamental, necessary process in modern societies. The sludge it generates is processed in digestion towers to produce gas. The sludge must be dewatered and incinerated in following steps. The dewatering process is often hindered by persistent, crystalline precipitates formed from the digested sludge. Typical precipitates include phosphates mixed with ammonium, magnesium and sometimes iron ions leading to rock-solid Struvite scale deposit (magnesium ammonium phosphate). In practice, precipitates lead to costly and time-consuming cleaning due to the scaling.

The new ROPUR RWI-8000 was engineered to specifically prevent this cost intensive scale to happen. Using the RWI-8000 in real case applications as well as in R&D multitests, revealed that the ROPUR Antiscalant RWI-8000 neutralizes mineral particles by 94.1 to 99.4 % on average. The particle concentration was drastically reduced following the use of RWI-8000, drastically reducing the costly cleaning frequency.

Application

ROPUR RWI-8000 is approved for use in waste water treatment plant at dosage level ranges from 20 – 50 ppm as delivered, with an optimum efficiency versus ration around 35 ppm. The dosage is proportional to the feed water ions composition. ROPUR RWI-8000 is easy to use, safe to handle and safe to store for several months.
