Pretreating Wastewater: Good Practice In Cosmetics Production

A wastewater treatment program developed by Veolia optimizes water management at a L’Oreal cosmetic manufacturing plant by pretreating wastewater, resulting in reduced energy consumption, chemicals usage, and sludge production.

Detailed Description

 

In a bid to achieve its environmental sustainability objectives, L’Oreal Manufacturing Indonesia was keen to address and introduce solutions for safe wastewater disposal. L’Oreal Manufacturing Indonesia turned to its partner Veolia, a global professional water solutions provider, to help design and implement a complete wastewater treatment plant for L’Oreal’s new facility.

The water challenges Veolia identified included a low flow rate, high concentration levels of oil and grease, and high concentration levels of chemical oxygen, which can lead to a higher level of organic pollutants in the wastewater.

The wastewater from the cosmetic manufacturing plant mostly contained organic industrial waste matter and therefore needed a special pretreatment process before discharge. The high concentration of suspended solids and fats present in the wastewater also required a longer time to decompose due to its complex components.

Taking all these factors into consideration, Veolia designed and proposed a complete wastewater treatment plant that featured three of its advanced water technologies. The wastewater treatment plant resulted in reduced energy consumption, chemicals usage, and sludge production.
