By 20 Juli 2021case, healthcare, rvf

The customer
The company is one of the world’s leading manufacturers of soaps, deodorants and hair care products. It has a history of over a century and the production headquarter is located in Italy.

The customer’s needs
Because of the increased volume of production of water from reactor washing and the need to foresee a drainage to sewage, the company has decided to expand the previous treatment plant consisting essentially of a biological oxidation.

The solution provided
The solution provided to achieve this goal is a vacuum evaporator type Evaled RV F 40, with a distillate production capacity of 40 m3/day.

RV F is the line of mechanical vapor recompression evaporators designed to reach the highest level of reliability in heat transfer, with minimum impact in terms of fouling and scaling and a wastewater concentration up to the salts solubility limits. RV F is also the evaporators line with the lowest energy consumption.

In this specific installation, the evaporator has been provided with a rental formula of 5 years along with the EVAtop full service pack which includes a remote assistance, maintenance, spare parts, lab analyses, chemicals etc.

EVALED®️ RV F evaporators can be remotely monitored and controlled through the HUBGRADE/EVAlink digital platform.

The solution achieved

  • The distillate produced by Evaled is sent to a biological oxidation system MBBR, sand filters and coal and then drained into the sewer
  • Concentration factor: 5 – 7 times
