Recirculation pumpinstallation

Landia propeller pumps are designed to pump large amounts of water at low back pressure. The pump is most often used in sewage treatment plants for recirculation of activated sludge in process tanks, but it is also used in drainage and in recirculation in fish farming plants.

Suck it up, pressurize it and send it to the treatment plant. In theory, this should be a straightforward job for pumps at a lift station. However, as we all know, the curse of so-called ‘flushable’ products in our sewer systems is also proving that some so-called ‘non-clogging pumps’ are getting clogged.

At Yorkshire Water’s new £50M Huddersfield Energy and Recycling Facility (E&RF), the digester mixing system from Whitchurch-based Landia is ensuring that total gas production can reach its anticipated 22,192Nm³/d (normal cubic meter/day).

Throughout Ohio there is a large a number of meat/food processing plants and municipal sites whose wastewater system is plagued by fats, oils, greases (FOG) and debris.

Landia supplied the first mixers for sewage treatment plants in the 1980s and today you will find Landia products at sewage treatment plants worldwide. The wastewater industry is growing year by year and we are keeping pace. When you contact Landia, you will speak with staff who know the industry, and who knowsand understand the wastewater industry.

An automated mixing system helps an Illinois treatment plant improve biogas production and increase volatile solids destruction.

At a landfill’s leachate treatment centre, where floating biomass was reducing the plant’s throughput, the introduction by Viridian Systems of a new mixer has created annual savings on chemicals of around £85,000.

If we took a short trip forward in time to 2040, and then looked back at how some organisations in the water industry successfully achieved Carbon Net Zero, it’s likely you’ll see a large four-letter word: NIGG.

At Valley Center Wastewater Treatment Plant, and at an increasing number of facilities across Kansas, the decision to buy the more expensive equipment at the outset is proving to be the most economic. Savings in long-term maintenance are important, but in the shorter term, energy savings are fundamental.

When Pittards, the leading leather goods producer, moved part of its manufacturing process from Leeds to Yeovil, they made very sure that its long-serving wastewater pumps went with them.
