Estimating the occupancy of different caravans or mobile homes is more difficult. Generally, it is best to plan for peak occupancy, therefore the normal size of caravan used on site of in general should be ascertained. They have normal occupancy numbers assigned to them and these can just be multiplied by the figures above.

How do you calculate the correct size of Petrol/Oil Interceptor or Separator that you require?

What are the different types of Petrol/Oil Interceptor (Separator) and what is the difference between them?

What is the difference between Class 1 & Class 2 Interceptors or Separators?

What is the difference between COD and BOD in sewage treatment?

What is the difference between ‘Effluent Standard’ & ‘Stream Standard’ in sewage treatment?

The BMS Aerotor is actually a next generation RBC, with all the advantages of traditional RBCs such as low maintenance costs and power requirements with none of the disadvantages such as one sided growth placing eccentric loads on the shaft, flow bypass in shock loading conditions and lack of aeration…

Dry Weather Flow is in essence the sewage flow, from a premises without the addition of any surface water.

Do you have a recycling solution for car/truck wash water with no discharge so that we do not have to get a discharge license or if we are not granted one?

We do indeed have solution for above ground sewage treatment in the form of the BMS Blivet Package Sewage Treatment Plant. One of the main features of our Blivet package sewage treatment system is that it can be placed above ground free standing with no extra supports.

A Package sewage treatment plant is a completely self contained system for sewage treatment that is ‘plug & play’ and should incorporate the following elements in one outer tank;

When calculating the size of a primary settlement tank for domestic type sewage e.g. from a house, school, hotel, camp site or base etc.

We can certainly design a system to handle these uneven flows. A sewage system prefers to have smaller regular flows rather than irregular large once off flows.

Parallel/lamellae plates radically increase the surface area in a given area. A unique feature of the BMS Blivet is the utilisation of lamella plate settlers in both the Primary Settlement and Final Settlement Zones. BMS worked with Dr. Michael Rodgers from the University of Galway to adapt parallel plates for use in sewage treatment…

When calculating the size of a primary settlement tank for domestic type sewage e.g. from a house, school, hotel, camp site or camp etc. you are looking to achieve a set upward flow velocity. In the case of a horizontal settlement tank you are generally looking to achieve an upward flow velocity of less than 0.9 m/hr. To do this you need to provide an adequate surface area.

A lot of sewage treatment plants are installed in the lowest area of a site to try and achieve gravity flow into it. However, with more intense rainfall becoming the norm, low lying areas can often be prone to surface flooding. ometimes large areas of sites can be subject to flash flooding and ponding.

The good news is Butler Manufacturing Services can offer a number of different solutions…

The level of maintenance required after installing a surface water attenuation, infiltration or SuDS system is a very hot topic especially when the local municipal authority will be taking the area in charge and will have to look after maintenance in the future. The good news is that BMS have pioneered two different ways to make an attenuation, infiltration or SuDS system essentially maintenance free.
