TYPE OF SLUDGE 

 

There are several sludge characteristics that have a great influence on the costs of sludge treatment.

The water content is very important as it determines the sludge volume and therefore feasibility and costs of transportation and disposal.

The solids and water content of sludge depends on the type of sludge (e.g. primary sludge, waste activated sludge, chemical sludge) and the type and quality of its treatment (e.g. sludge digestion) and on the method of sludge thickening and dewatering.

The chemical composition of the sludge also depends on wastewater characteristics and the wastewater treatment method. 

 

 

SLUDGE TREATMENT

 

The main waste generated in a municipal waste water treatment plant is the wastewater sludge that is removed from mechanical, biological and chemical wastewater treatment processed.

The amount of sludge depends on the type of treatment, the connected population and population equivalents, and wastewater characteristics. Wastewater characteristics and specific sludge production vary from country to country and from region to region. 

 

 

 

SLUDGE SOLUTIONS

 

BIOMICROBE  offers the complete program of sludge treatment equipment:

 

  • Sludge Screening

inline automatic self-cleaning screen filters, Bar screens, rotery screen drums are suited to a variety of filtration and separation processes                  

where water is the principle medium. With a wide range of screen element types and several screen cleaning processes, there will be a                    

Biomicrobe system combination to befit most applications.

Full stainless steel construction ensures a long service life and the ability to                   withstand rigorous process applications.

Simple, robust electro-mechanical controls and electronic controller ensure excellent reliability and low maintenance requirements. 

 

  •  Sludge Thickening

Polymers are added to the thin sludge for flocculation. Generation of large and strong flocs depends on the right choice and dosage of polymers, and on intensive mixing of polymers and sludge. Sludge water is released between the flocs and drains by gravity through a filter medium (cloth or fine screen) while flocs are retained thereon.

 

  •  Sludge Dewatering

A further reduction of the sludge amount is mostly necessary after the thickening. 

The liquid sludge has to be dewatered and has to conform to a dry and porous form. Dewatering can be done naturally dry beds, solar (drying), however this is only possible during a long period of time. Faster and smaller, but also more cost intensive, are machine processes such as, Belt-press, Filter-press, Dewatering hopper, Dewatering drums, Screw press separators, Decanter centrifuges, Dewatering presses

 

  •  Sludge Removal true benificial bacteria,

Sludge can be redused true adding additional bacteria to your wastewater 

This is a simple, efficient and affourable methode to meet regulations standards. 

 

  • Sludge Composting

reuse it for agricultural purposes, enriching the soil without fossil fertilizers and reducing the carbon footprint from fertilization;

 

  • Sludge Biogas

recover its energy potential in the form of biogas, high amounts of COD are required
