Tittle:
Technology for dewatering of biological and dissolved air flotation (DAF) sludges for the municipal and industrial sector
Summary:
A Dutch technology centre for sales and service of centrifuges is offering a centrifugal extractor and vertical centrifuges for dewatering waste water sludge and separating waste water flows. The technology can be applied in municipal-, and industrial waste water treatment facilities. The company offers a commercial agreement with technical assistance to experienced partners with a complementary product portfolio in various countries in Europe.
Description:
The Dutch company is, within a group of companies, responsible for the communal water and industrial sector in Europe, Russia and the CIS countries. The company obtained a major market share in the environmental sector with its decanter centrifuges in various industries such as food, chemicals, textile and paper industry as well as the public sector. The company works with local dealers and agents.

The extractors and centrifuges on offer vary in capacity from 1m3 up to 150m3.

The main areas of environmental application for the decanter centrifuges are:
- Dewatering of sludge from municipal and industrial waste waters (paper; tanning, textile, quarrying industries, etc). This can be either biological, primary or secondary aerobic or anaerobic treated, as well as physical chemical dissolved air flotation (DAF) sludge.
- Sludge from water treatment plants
- Drilling mud recovery
- Supply of mobile platforms or skids for third-party sludge dewatering
- Tank oil residues and slop oils from the petrochemical industry
- Pig and cattle manure
- Waste oil
- Treatment of butchery by-products
- Plastic waste recovery
- Paint waste recovery
- Steel industry: Filtering of waste water, gases and cooling water at the rolling mill
- Potato processing industry: cleaning of water used for washed and cutting the potatoes, including recovery of starch.

The company´s main market is the market for the treatment of waste water / sludge from municipal-, and industrial waste water treatment facilities.

Principles of the separation system:
The decanter is used for the separation of two or more phases of different specific gravity, in particular for the clarifying of liquids in which suspended solids are present. The separation of solids and liquids takes place within a cylindrical / conical rotating drum, upon the periphery of which the heavier solid phase collects and is continually removed by the internal conveyor. A poly-electrolyte, suitably chosen for its type and specific characteristics, may be added to the product being fed to the machine in order to improve the solid-liquid separation. The polyelectrolyte favours the aggregation and thus the easier capture of the solid particles. A polyelectrolyte is not always compatible with products being processed. It is generally used in purification processes for the drying of sludge, but not in intermediate product conversion processes, and even less in the processing of foodstuffs.

General production features:
- Since its early days the main market has been the agricultural sector. This sector is characterised by seasonal demands, pushing maximum production, with no downtime allowed for maintenance. breakdowns need to be avoided at all costs. Equipment had to be robust, reliable and easy to maintain. These features characterise the companies equipment today.
- Nowadays robotic manufacturing techniques are used for welding and machining. This enables consistent high quality and accuracy of fabrication.

The end-users / customers are generally the following target groups:
- Technical managers responsible for waste water treatment plants (WWTP´s) in industries and municipalities
- Contractors of industrial and municipal WWTP´s (technical / procurement department)
- Farmer´s cooperatives
- Consultants and engineering companies, including engineering, procurement and construction (EPC) contractors, for WWTP´s.

Potential partners are most likely to be located within the following target groups:
- consultants and engineering companies, both national and international,
- large contractors, active in the field of building WWTP´s on a turn-key basis,
- small to medium contractor building local WWTP for the industry,
- agricultural cooperatives and water boards.

The partner will be responsible for start-up, commissioning, service (installation and maintenance) and client training for a specific region.
Advantages and Innovations:
By applying decanter centrifuges to dewater waste water sludge and separate waste water flows, substantial savings can be achieved based on waste emission reduction and reduction in volume of the solids disposal.

The unique selling points of this companies solutions can be summarised as follows:

- The company offers high-tech solutions to solve virtually any problem concerning separation, clarification and dewatering, with the safety and reliability that ensue from state-of-the art production.
- The company is flexible, offers good delivery times and has a large stock.
- Ongoing co-operation with the end users for the development of innovative products.
- The company is prepared to guarantee all in maintenance costs for only 6% of the total investment costs per year for a period of 5 years. The maintenance costs are so low due to the quality of the production process and materials. Furthermore, the company has a unique parts exchange program in operation. Customers who attend this program are able to change a scroll within 48 hours. The worn scroll will be reconditioned, while a ready reconditioned scroll is on stock. Therefore there is less need to install a stand-by decanter to overcome a typical downtime of 3 weeks or more to change a scroll assembly. Furthermore costs for exchange usually are only 30-50% of the new price.
- The centrifuges are closed units: clean, odour tight and safe processing.
- The company customizes its centrifuges according to the wishes of the client.
- High grade stainless steel, is used such as AISI 1.4470 Duplex, AISI316 or AISI304 for all wetted parts (AISI: American Iron and Steel Institute)
- The centrifuge operates stand-alone and does not require to be operated by personnel
