Biological urinal dosing system

30 January 2018

Failure to address the problem of hard water in urinal systems is a major cause of blockage and noxious odours, and is responsible for soaring sanitary control costs in the UK, according to Cleveland Biotech (CBio).

With 60% of the UK’s water classed hard or very hard and an increasing number of urinals being installed in offices, pubs and restaurants, the biotech company warns that water-based solutions can only be cost-effective and hygienic when derived from low volume application.

James Patterson, managing director at CBio, said: “Nobody enjoys walking into a men’s bathroom and immediately being struck by the foul odour of blocked urinals, particularly if the bathroom is in a place of work or near a food station. It’s worse again if the urinals are overflowing and the floor is half an inch deep in urine and water.

"This problem can impact negatively on business, leaving a poor impression when existing and potential customers visit the premises. If you couple this with the soaring cost of uncontrolled urinal-flushing, which can be as much as 200 litres per hour, it becomes an enormous hygienic and financial burden.

“Unheeded, hard water is high in dissolved minerals, specifically calcium and magnesium. Historically, people have enjoyed the healing benefits of hard water – for example the mineral-rich springs in Bath. However, when hard water is left to stand, as it often is in urinals, the dissolved minerals in it solidify as the moisture evaporates and these solidified minerals leave what we know as limescale. Deposits from the urine also crystalize onto the pipe and cause additional blockages, bacteria and odour.

“Everybody wants to save money and cut water usage, but when dealing with urinals, saving money often leads to the problem of scale. Promoting good hygiene whilst cutting water costs means finding a solution that systematically ensures less water is used while ensuring both visible and out-of-view areas are always clean and free of noxious odour,” said Mr Patterson.

CBio, a leader in grease management, working with blue-chips such as McDonalds and the Young’s Brewery has developed a biological urinal dosing system – BioGent – that is said to tick both the financial and hygienic boxes. It functions by reducing the number of flushes required and – instead of just masking the smell – addresses the root causes of the odour by proactively attacking the scale build-up.

BioGent is claimed to reduce water costs by up to 90% and help ensure compliance with ‘The Water Regulations 1999’, which specifies a maximum water usage of 7.5 litres per urinal bowl per hour. Uncontrolled urinals can flush every three minutes resulting in up to 200 litres per hour – costing as much as £6,800 per annum.

BioGent is safe to use, cost effective and environmentally friendly, and part of the BioGent service includes quarterly visits from a specialist engineer to ensure the system is fully functional in achieving its objective.
