wastewater treatment
Facultative Lagoons are systems that are low-cost and, with the use of our products, can be a highly efficient alternative for wastewater treatment, especially in warmer climates such as found in Portugal. When these lagoons are bio-augmented, a BOD reduction can be attained for raw screened or primary settled domestic wastewaters

Explanation:
http://www.kurita.com.br/adm/download/Etapas_do_Tratamento_d...
Gradeamento
Etapa na qual ocorre a remoção de sólidos grosseiros, onde o material de dimensões maiores do que o espaçamento entre as barras é retido. Há grades grosseiras (espaços de 5,0 a 10,0 cm), grades médias (espaços entre 2,0 a 4,0 cm) e grades finas (entre 1,0 e 2,0 cm) que têm pôr objetivo reter o material sólido grosseiro em suspensão no efluente. As principais finalidades do gradeamento são: proteção dos dispositivos de transporte dos efluentes (bombas e tubulações); proteção das unidades de tratamento subseqüentes e proteção dos corpos receptores.
Desarenação
Etapa na qual ocorre a remoção da areia por sedimentação. Este mecanismo ocorre da seguinte maneira: os grãos de areia, devido às suas maiores dimensões e densidade, vão para o fundo do tanque, enquanto a matéria orgânica, de sedimentação bem mais lenta, permanece em suspensão, seguindo para as unidades seguintes.
As finalidades básicas da remoção de areia são: evitar abrasão nos equipamentos e tubulações; eliminar ou reduzir a possibilidade de obstrução em tubulações, tanques, orifícios, sifões, e facilitar o transporte do líquido, principalmente a transferência de lodo, em suas diversas fases.

Screening
The influent sewage water is screened to remove all large objects like cans, rags, sticks, plastic packets etc. carried in the sewage stream.[5] This is most commonly done with an automated mechanically raked bar screen in modern plants serving large populations, whilst in smaller or less modern plants a manually cleaned screen may be used. The raking action of a mechanical bar screen is typically paced according to the accumulation on the bar screens and/or flow rate. The solids are collected and later disposed in a landfill or incinerated. Bar screens or mesh screens of varying sizes may be used to optimize solids removal. If gross solids are not removed they become entrained in pipes and moving parts of the treatment plant and can cause substantial damage and inefficiency in the process.[6]:9

Primary treatment
In the primary sedimentation stage, sewage flows through large tanks, commonly called "primary clarifiers" or "primary sedimentation tanks." The tanks are used to settle sludge while grease and oils rise to the surface and are skimmed off. Primary settling tanks are usually equipped with mechanically driven scrapers that continually drive the collected sludge towards a hopper in the base of the tank where it is pumped to sludge treatment facilities.[6]:9-11 Grease and oil from the floating material can sometimes be recovered for saponification.
The dimensions of the tank should be designed to effect removal of a high percentage of the floatables and sludge. A typical sedimentation tank may remove from 50 to 70 percent of suspended solids, and from 30 to 35 percent of biochemical oxygen demand (BOD) from the sewage.
