The processes used in municipal wastewater treatment plants are often classified as part of primary, secondary or tertiary. Primary Treatment: Wastewater entering a treatment plant contain materials that could clog or damage pumps and machinery. These materials are eliminated through trellis or vertical bars, and burned or buried after being collected manually or mechanically. The wastewater then passes through a crusher, where the leaves and other organic materials are crushed to facilitate further processing and disposal.

House of sand
In the past, were used deposition tanks, long and narrow, in the form of channels, to remove inorganic or mineral matter such as sand, silt and gravel. These cameras were designed so as to allow the inorganic particles of 0.2 mm or more be deposited into the fund, while the smallest particles and most organic solids that remain in suspension continued their journey. Today, most cameras used are the spiral-flow aerated with hopper bottom, or clarifiers, mechanical arms bearing makers scrape. Mineral residue is removed and poured into landfills. The accumulation of these wastes can range from 0.08 to 0.23 m3 per 3.8 million liters of wastewater.
