Kehadiran telur cacing parasit di lingkungan menjadi perhatian sejak badan kesehatan dunia (WHO) mempublikasikan versi baru dariPedoman untuk Penggunaan Kembali Air Limbah, Materi Fekal, dan Greywater untuk Pertanian dan Perairan tahun 2006 yang menjadikan telur cacing parasit sebagai polutan yang perlu mendapat perhatian. Batas ekuivalen telur cacing dalam air limbah yang digunakan kembali adalah 1 telur/L sedangkan jumlah maksimum pada lumpur adalah kurang dari 1 telur/gram total solid (TS). Telur cacing parasit, khususnya Ascaris spp., menjadi ancaman dalam pemanfaatan kembali air limbah dan lumpur sebagai produk sampingan Instalasi Pengolahan Air Limbah Domestik (IPALD) karena sifatnya yang resisten menyebabkan waktu ketahanan telur cacing lebih panjang dibandingkan mikroorganisme lain.
With the development of the restaurant industry, a series of environmental problems emerged, including high concentrations of oily wastewater. As a developing country, Indonesia has a large amount of effluent produced that is not processed but is discharged directly to the available pool. In order to handle restaurant wastewater, physical and chemical approaches can be combined with biological degradation (biodegradation). This biodegradation can be increased by bacterial acclimatization, namely by the addition of microorganisms that have been developed that can efficiently degrade pollutants in a contaminated environment. Stages of research were carried out by propagation of bacteria (Seeding), then the acclimatization process was carried out to adapt bacteria to waste, biodegradation process, and calculate the growth rate curve of microorganisms. It was found that the half-saturation constant of mixed culture microorganisms to treat restaurant waste was 41,336, with a maximum growth rate of 0.124 per day.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
