Single-pass Sea Water Cooling

Biofouling reduction

An alternative to cooling towers in the use of single-pass sea water cooling, where sea water is pumped through a heat exchanger, before being returned to the sea. This has the advantage of not leading to a heghten concentration level of scaling in the water, which in turn leads to scaling. However, these systems tend to suffer from problematic biofuling on the heat exchanger surfaces.

Government City Hall, Hong Kong

The cooling system in this government building was sufferning continualy efficiency reduction due the the biofouling on the heat exchanger blocking heat transfer and impeding its operation. After monitoring the temperature, flow rate and power consumption (without HydroFLOW®) for a year, a unit was installed and the parameters monitored.

It was found that while the efficiency of the unprotected system gradually dcreaased, when protected by HydroFLOW® the efficiency of the heat exchanger actually actually increased, leading to huge savings in energy and electricity costs.

  • Electricity saving over trial period of 25,780 kWh
  • Represents a saving of 17.3%
  • Saving over per year of $23,202 dollars

Limescale Reduction and Removal

Factories and manufacturing equipment produce large amounts of heat than need to be dissipated. Cooling systems are vulnerable to limescale, whether that be cooling towers, heat exchangers or cooling channels withing the production equipment itself. Limescale blockages can reuire expensive cleaning procedures and lead to excessive downtime and lost production. HydroFLOW can keep your equipment running smoothly.

Plastmann Corporation, Injection moulding

The Plastmann Corporation had a set of four cooling towers serving 3 chillers and a bank of 40 injection moulding machines. The factory used well water with a hardness of 10 grains (about 170ppm), meaning the chillers and moulds would continually suffer from scale. Despite preventative cleaning every 3-6 months, at least one or two injection machines would block, overheat and need to be stopped in the intervening period.

  • 50 -75% Savings on Maintenance Costs
  • Chemical usage reduced to near zero
  • Injection machines run without stoppage for a year.

Trucking Company Steam Boiler

Limescale Reduction and Removal

This commercial trucking company from Rosemount, Minnesota, USA, operated a 60 horse power low pressure natural gas steam boiler, with the steam used during the truck wash process. The water used in the boiler was well water with calcium carbonate hardness of over 200 PPM. A water softener reduced the hardness to roughly 30 PPM. Antiscalant was also used. Due to excessive scale accumulation in the boiler, even with softening and chemical usage, the head of maintenance decided to evaluate HydroFLOW®’s ability to descale the steam boiler and prevent further scale formation. A unit was installed on August the 1st, 2013. The boiler was not cleaned on installation to allow for evaluation of the HydroFLOW® unit's ability to remove existing scale.

Results

After 6 months the boiler was inspected. Flakes and layers of scale were gradually being removed and the remaining scale was very brittle. Stack temperature has dropped from 296° F to 272° F in 6 months, which demonstrates an 8% increase in heat transfer efficiency. The efficiency is expected to further increase as scale continues to be removed from the system. The removal of scale can be greatly accelerated if the steam boiler will be fed with unsoftened water, however the water softener was not turned off s it serves the entire truck wash system and there is no bypass for the boiler feed.

Limescale and Biofouling Reduction

Cooling towers are vital in a large range of applications, from air conditioning in residential or commercial buildings to large scale cooling in heavy industry and power generation. Cooling towers suffer from a number of problems which HydroFLOW® can address. A major issue is limescale on the heat exchangers, which reduces cooling efficiency and requires ongoing maintenance expenses. Additionally, there can be problems in the tower itself, either due to limescale again, or due to bacterial or algae growth. Treatment with HydroFLOW® can prevent hard scale encrustation in the heat exchanger and on the tower, and reduce the biofouling. This allows operation with lower (or zero) chemical treatment and higher cycles of concentration, reducing the money spend on sewage and drain down as well as chemical treatment.

RB1 Building, Brasil

The cooling tower shown below, on the RB1 building in Rio de Janerio, Brazil, shows an example of the possible benefits of HydroFLOW®. With HydroFLOW® protecting against scaling on the heat exchanger and the tower, the tower could increase the cycles of concentration from 4 to 25 cycles, with a corresponding decrease in make-up water and the associated water and sewerage charges. The thermal efficiency was also maintained at a high level – before protection with HydroFLOW®, the tower required four recirculation pumps during the summer months to reach the required cooling level. After treatment, the tower could be run with only three pumps, giving a 25% decrease in the associated costs.

  • Cycles of concentration up from 4 to 25
  • Decrease in make-up water and sewage charges
  • 25% reduction in pump power requirements

Swimming Pool Treatment

Backwash Reduction and Improved Filtration

Ensuring that water quality is at the highest level is an ongoing battle for operators of pools of any size, from Olympic pools and water parks to household spas. In any pool the two main challenges are maintaining efficient filtration of the water, and keeping the bacterial count low without adding too much chlorine. HydroFLOW® uses non-chemical flocculation to help existing filters work more effectively. The water becomes clearer, and the filter itself becomes easier to clean. This means that the amount of water wasted on backwashing – and the energy and chemicals used to heat and treat it – can be dramatically reduced. Reductions in the total amount of backwashing commonly reach 66%, and the savings on water, sewage and chemical charges can be huge. Additionally, as chloramine levels are lowered, the “Swimming Pool Smell” and eye irritation is also reduced.

500 Cubic Meter Outdoor Pool

The pool shown below is a 500 cubic meter outdoor pool. Before treatment with HydroFLOW®, they were using 34.3 kg of chlorine/ day and 4.3 kg of acid. They were backwashing an average of 1.5 times per week, equivalent to 18 cubic meters per week. The pool was treated with HydroFLOW® for a trial period of 6 weeks. Over this time, the chlorine used was reduced by approximately 47% and the acid used was reduced by around 70%. Backwashing frequency was reduced to an average of 0.5 times per week, corresponding to a 66% reduction in the amount of backwash water. The drop in backwash water volume and chemical use had a knock-on effect of making the maintenance of the pool easier and more convenient.

  • 66% reduction in backwash
  • 47% reduction in chlorine
  • 70% reduction in acid use

Biofouling Removal

HydroFLOW® can assist not only with treatment and prevention of limescale, but also with eradication of unwanted biological deposits, known as biofouling. Biofouling refers to the problem of biological material such as bacteria collecting on the surface of equipment and impeding its operation. Commonly bacteria cling to surfaces in a gelatinous layer, which among other problems, can impede heat transfer and reduce efficiency. Biofouling is particularly a problem in food production or in other industries dealing with biological material (such as paper production), or in cooling systems operating on naturally sourced water from the sea or rivers. HYDROPATH’s patented technology can remove existing biofouling in heat exchangers and pipework and prevent its reoccurrence, saving time and money on maintenance and cleaning.

Meat Factory, Ukraine

An example of the benefits of HydroFLOW® is shown below. This Ukrainian meat processing plant had a severe biofouling problem in the steam boiler for seven years. Frequent shutdowns were required for deep cleaning which would only temporarily solve the problem. After three months of treatment with HydroFLOW®, not only had the layer of biofouling been removed, but the lingering unpleasant odour had disappeared and the bacterial contamination of the output steam had been eliminated.
