Andrews Boilers are very well- versed when it comes to anaero- bic digestion and as such have assisted water authorities up and down the country for a number of years. This knowledge and expertise recently led to the spe- cialist hire company working with Welsh Water via a third- party contractor by providing a solution be tting of their treat- ment process. Anaerobic digestion is a form of biological wastewater treat- ment used to reduce the number of organic wastes by using microorganisms to break down biodegradable material. This process is commonly used to treat sewage sludge and will pro- duce a biogas that can be con- sumed as a source of renewable energy. In this particular instance, the contractor overseeing the pro- ject sought a solution for their new digestor using an imported bacterium rarely used in the UK. Before a course of action was decided, an Andrews engineer attended a design meeting to gain a better understanding of what exactly was required. Thereafter, a speci ed solution was settled upon including the equipment and accessories needed in order for it to work. A 500kW boiler unit was sub- sequently provided along with a Andrews Boiler Hire assist Welsh Water treatment process heat exchanger, hoses, a pump and an expansion vessel. The equipment was installed and commissioned shortly after dis- cussions with the client were undertaken, meaning its impact was immediate. It was decided that the bio- mass would be pumped from the reactor to a nearby heat exchanger, where it was then heated. This phase of the process required careful monitoring, with the biomass heated and thermostatically controlled to ensure it didn't exceed the ideal temperature. Failure to take such precautions would have seen temperatures rise beyond the desired level and potentially kill the bacteria. Although excessive warmth would have been disastrous, it was still important to ensure the biomass was heated above a cer- tain temperature as the process would have been completely ine ective otherwise. The exper- tise of Andrews, however, ensured this scenario was avoided and allowed a major customer to achieve the results they were looking for when the task was originally undertaken. 0800 211 611 At Sykes Pumps we possess the broadest range of equipment available, from general purpose pumps to silenced, submersible and high performance units.

For the past four years, Sykes Pumps has been involved with the Hinkley Point C project, pro- viding a range of submersible, diesel and electric pumps for var- ious elements of the develop- ment program. The leading hire pump spe- cialist will install the latest pair of custom-built pumps sold to EDF Energy as part of the water man- agement strategy. The latest installation involves two 22kW pumps to work in conjunction with a silt separation process. Sykes Pumps has provided cus- tom-built automatic self-priming solutions to enable instant start up and pumping on demand, along with a sophisticated control sys- tem that ensures the required level of ow is pumped through the sys- tem. Each WMZ pump system has been designed to adjust the ow rate aligned to groundwater and weather conditions so that the capacity in all the lagoons can be maintained at optimum levels at all times. Bob Lima, who has been responsible for commissioning the pumps, commented: "Kier BAM provided us with a maxi- mum ow rate for each WMZ. The controls tted mean that the pumps are only in use as much as they need to be." Sykes Pumps has provided training for the Tier 1 team on site and has a four-strong team of engineers permanently based at Hinkley Point C to carry out the planned servicing. Peter Pearson from Kier BAM, commented: "Sykes Pumps was able to design a exible solution around the speci c demands of our water management strategy, delivering an installation that addresses both the need to con- trol groundwater and the impera- tive for limiting unnecessary energy consumption whilst ensuring we uphold the highest environmental standards."
