Water Filters

Penadaran Village is a village in Gubug District, Grobogan Regency, Central Java Province. The dry season makes residents in Penadaran Village experience problems with clean water sources. The purpose of community service is to make filters and provide clean water reservoirs for the residents of Penadaran Village. The implementation methods used are: (1) Conducting Tuntang River Water Quality Test, (2) Designing a scheme for clean water filters and reservoirs, (3) Making clean water filters and reservoirs. The location is in Kedungkakap Hamlet, Penadaran Village. The implementation time is August – October 2021. The results of the implementation of community service, obtained the results of the Tuntang River Water Quality Test, namely, Iron: 0.496 mg/L, COD: 301 mg/L, Chloride: 7.30 mg/L, manganese: 0.502 mg/ L, the river water filter scheme uses a system with 3 settling tanks and 2 mixed bed tubes. The shelter uses a 3300 ml Toren with a tower as high as 3 m from the ground. There are 17 families who have received clean water supply from the new source

Water Filters

Tegallega Village, Warung Kondang District, Cianjur Regency has a problem regarding the availability of clean water, the water used by residents comes from the Cimanceuri River or dug wells where the water is relatively cloudy, even though the use of dirty water has the potential to cause various health problems, such as cholera, dysentery, typhus, and tuberculosis and other diseases. The availability of clean water has always been one of the characteristics of community welfare. How not without clean water it is impossible to realize a prosperous society, a physically and mentally healthy society as a form of participation in developing public health. This activity method in community service uses a follow-up study method with a participatory approach in community service, the team conducts training on how to make simple water filtration that can be used as a source of clean water for families by using plastic bottle waste and other environmentally friendly materials that residents can find around environment in making the dirty water filter. The results of this Community Service Activity went smoothly and were greeted with great enthusiasm by the residents because the practice of making water purification equipment made with materials such as pebbles, coconut fiber, charcoal, fibers, and sponges functioned well from the water which was originally colored cloudy turns to be clearer and odorless.

Organic Removal

A mathematical model is proposed to predict the removal of dissolved organic substances and the consumption of dissolved oxygen by attached biofilms in an open-channel flow. The model combines the biofilm equations with the conventional Streeter–Phelps type equations of river water quality by considering the mass transfer of organics and oxygen in the river water through the diffusion layer into the biofilm. It is assumed that the diffusion and reaction within the biofilm are of steady-state, and follow Monod kinetics. The model is solved numerically with a trial-and-error method. The simulation results of the model for an ideal case of river flow and biofilm show that the organic removal rate and oxygen consumption rate caused by the biofilm are greater than that by suspended biomass. The effects of diffusion layer thickness, flow velocity, and biofilm thickness on the change of river water quality are discussed.
